The common name for the mineral formed from calcium carbonate is calcite. Calcite is a prevalent mineral found in sedimentary rocks, particularly limestone, and is also a major component of marble. Its crystalline structure can appear in various forms, such as rhombohedra, and it exhibits a range of colors, including clear, white, and hues due to impurities. Calcite is widely used in construction, agriculture, and various industrial applications, particularly in the production of cement.
